Here's a topic guaranteed to start controversy. Which Linux distribution is best? It all depends on your criteria for judging. Even then the topic is highly subjective. Here are a few nominees for "best distro" in specific categories.

Archlinux has many problems. Stability, blindly following upstream, lack of leadership, removing the KISS aspect of the distro (what the distro was originally about).

Gentoo solves all these problems

What are you kidding me? Gentoo is also bleeding edge and they break shit all the time. The key is to not install X, wireless or audio. That's how you avoid 95% of breaks. Of course that means you can't run it as a desktop .... yep.

Also, Gentoo is actually open. There are no secret sites, there are no secret mailing lists, users are not restricted from posting on the -dev mailing list

That doesn't bother me at all. I don't buy into the 'everything must be open' philosophy. Developers should be allowed to have private conversations without being castigated.

Anyways I'll take pacman and a fast install over what Gentoo offers. But sadly the occasional Linux work I do is usually on CENT. I've been spoiled by pacman and the Arch wiki. CENT documentation is awful for how common it is.
